html - background-image css does not show in img tag -


the responsive image in bootstrap html not show:

<div class="container-fluid">     <div class="row">         <div class="col-sm-12">             <img class="myimg img-responsive"/>         </div>     </div> </div>

css

.myimg {     background-image: url("http://images.wikia.com/worldlanguages/images/6/63/wikipedia-logo.png");     display:block;     height:100%;     width:100%; }

jsfiddle demo

<img src="..."> work, need define image in css.

this similar thread suggests using <div> , removing quotes in url(), did not help.

why not show?

you need set height of parents, , need background-size: cover

(demo)

html, body {     height: 100%; } .container {     height: 100%; } .row, .col-sm-12 {     height: 100%; } .myimg {     background-image: url("//lorempixel.com/200/200");     background-size: cover;     display: block;     height:100%;     width:100%; } .myimg2 {     background-image: url("//lorempixel.com/200/200");     background-size: cover;     display: block;     height:100%;     width:100%; } .myimg3 {     background-image: url("//lorempixel.com/200/200");     background-size: cover;     display: block;     height:100%;     width:100%; }

if responsively change background image, can so.

(demo)

html, body {     height: 100%; } .container {     height: 100%; } .row, .col-sm-12 {     height: 100%; } .myimg, .myimg2, .myimg3 {     background-size: cover;     display: block;     height:100%;     width:100%; } @media (max-width: 500px) {   .myimg {       background-image: url("//lorempixel.com/500/500/cats");   }   .myimg2 {       background-image: url("//lorempixel.com/500/500/business");   }   .myimg3 {       background-image: url("//lorempixel.com/500/500/transportation");   } } @media (max-width: 750px) {   .myimg, .myimg2, .myimg3 {   .myimg {       background-image: url("//lorempixel.com/750/750/cats");   }   .myimg2 {       background-image: url("//lorempixel.com/750/750/business");   }   .myimg3 {       background-image: url("//lorempixel.com/750/750/transportation");   }   } } @media (max-width: 1000px) {   .myimg {       background-image: url("//lorempixel.com/1000/1000/cats");   }   .myimg2 {       background-image: url("//lorempixel.com/1000/1000/business");   }   .myimg3 {       background-image: url("//lorempixel.com/1000/1000/transportation");   } }
